I have two problems. First, sometimes the van will not start on first try. I am not sure what this would be. It is usually after is has ran and warm. The second is the cooling system will not hold 20psi. I am not sure what could be leaking. It seemed like the head by the firewall on the passenger side was a little wet. I am not sure what typically could be leaking on the 3.5L?
Please advise.
